While members of my family might disagree, I would never pass up the opportunity to ride Monster Mansion. While the ride might not quite compare to Disney World's best themed rides, Monster Mansion is the closest that I have ever seen any other park get outside of Disney and Universal.
A few years ago, the park celebrated the birthday of Monster Mansion by giving several scenes a facelift, and it was very well done.
Monster Mansion has several great scenes throughout the ride, but there is one towards the end of the ride that could be frightening for children, so make sure to keep them seated close by.
